If I am understanding the code correctly, modifying these 3 lines should add laiden/oread spawn (or any other monster that spawns minions):
//dwMaxSummonsMonsterCount eax+64
//dwReSummonsMonsterTick eax+68
//dwMaxSummonsMonsterRange eax+6C
I THINK this is the code to repace it, making the spawn rate just about continuous, up to 100 mobs, and spawns them right on the boss monster:
mov [eax+64],00000063//dwMaxSummonsMonsterCount eax+64
mov [eax+68],000000FA//dwReSummonsMonsterTick eax+68
mov [eax+6c],00000000//dwMaxSummonsMonsterRange eax+6C
I've not tried it yet, almost time for DF here. I'll post how it works later.
